To solve any coordinate equations

Question - 

Given any coordinate equation , you have to solve that equation.

Example -

Input : a = 1, b = 5 , c = 4

Output : x1= -1 , x2= -4

Input : a = 1 , b = 0 , c = -1

Output : x1= -1 , x2 = 1

Approach - 

We solve this question with the help of shri dharacharya formulas.

Implementation -

 

//To solve the coordinte equation

#include<iostream>

#include<math.h>

using namespace std;

int main()

{

    int a,b,c;

    double d;

    cout<<"A coordinte equation is represented as : a*x^2 + b*x + c = 0"<<endl;

    cout<<"Enter the value of a : ";cin>>a;

    cout<<"Enter the value of b : ";cin>>b;

    cout<<"Enter the value of c : ";cin>>c;

    d=sqrt((b*b)-4*a*c);

    double x1,x2;

    x1=(-b+d)/(2*a);

    x2=(-b-d)/(2*a);

    cout<<"x1 = "<<x1<<endl<<"x2 = "<<x2<<endl;

}
